Quick Comparison

For Maryland property owners facing strict stormwater regulations, BayFilter offers a practical and cost-efficient solution to reduce pollutants while keeping maintenance manageable.

How the Stormwater Management StormFilter Works

1. BayFilter System

The BayFilter system is designed to capture pollutants effectively while minimizing the need for frequent maintenance.

Performance

This system is built to remove pollutants efficiently over extended periods ^[2]. Its hydrodynamic backwash mechanism ensures consistent performance by preventing the buildup and re-suspension of sediments, oils, and debris between cycles ^[3]. Additionally, it includes safeguards to avoid toxic or anaerobic conditions during dry spells ^[1][3]. These features not only enhance performance but also help reduce operating costs.

Cost

Compared to traditional filtration methods, the BayFilter system is more cost-efficient over its lifespan ^[1][3]. Its design reduces the frequency of maintenance, leading to lower overall expenses. On top of that, the system is straightforward to maintain, which adds to its cost-effectiveness.

Maintenance

Thanks to its self-cleaning design, the BayFilter system requires minimal maintenance ^[3]. An optional drain-down cartridge can eliminate standing water between storms, helping to prevent mosquito breeding and unpleasant odors ^[1][3]. When maintenance is necessary, tasks like inspections and cartridge replacements are quick and easy, requiring no specialized tools. This streamlined process minimizes disruptions and keeps long-term service costs manageable.

2. Other Proprietary Filtration Systems

While the BayFilter system focuses on outdoor, low-maintenance use, many other filtration systems are designed for indoor installation and come with specific requirements. These whole-house systems are typically placed indoors near the main water entry point to treat all incoming water^[5][7]. The location must be dry, stable, and easily accessible for maintenance, while also being protected from extreme temperatures and direct sunlight^[5][6][7]. These conditions are critical for proper setup and long-term functionality.

Before installation, certain parameters must be met. These systems operate within a water pressure range of 29–87 PSI and a temperature range of 39–86°F^[6]. Additionally, pre-filtration is necessary to remove particles smaller than 100 microns, achieved using an extra cartridge or a backwash filter^[6].

Compatibility with the system also depends on additional factors. For example, systems with automatic control valves need a 230V, 50Hz power outlet located within 10–15 feet of the tank. Installation costs for this setup typically range from $150 to $350^[4][6]. Moreover, a 3/4" or 1" drain line must connect to a non-pressurized sewer pipe for proper drainage^[6].

Advantages and Disadvantages

When it comes to stormwater management, understanding the pros and cons of different filtration systems is essential for property owners. Each system has its own strengths and limitations, which impact performance, cost, and scalability. Here’s a closer look at how these systems compare.

The BayFilter system operates using a gravity-driven design, which eliminates the need for electrical power or mechanical components. This simplicity not only reduces operational costs but also minimizes maintenance demands. Its modular structure allows for cartridge-based expansion, making it adaptable to various needs^[9].

On the other hand, other proprietary filtration systems often involve more complex setups. These systems typically require electrical power and professional servicing, which can significantly increase both installation and maintenance costs. While they can achieve total suspended solids (TSS) removal rates between 70–90%, their performance often depends on the specific design and the quality of ongoing maintenance.

Cost is another key factor that sets these systems apart. BayFilter’s straightforward design means lower upfront installation and maintenance expenses. However, for high-flow applications, multiple cartridges may be necessary, which could raise initial costs for larger properties. In contrast, many other proprietary systems come with higher initial costs and additional service fees over time.

Maintenance needs further highlight the differences. BayFilter systems require only periodic cartridge replacements once the 350-pound sediment capacity is reached^[10]. Meanwhile, other systems often demand more intensive professional servicing, especially due to their reliance on mechanical components and electrical systems.

Beyond these general differences, the BayFilter system offers additional advantages. With a flow rate capacity of 0.33–0.50 gallons per minute per square foot^[10], it is well-suited for a wide range of applications. It also removes approximately 95% of particles larger than 5 microns^[8], which is particularly beneficial for preserving water quality in landscaping and hardscaping projects.

Scalability is another area where BayFilter excels. Its modular design allows for easy expansion by adding more cartridges. However, for properties with extremely high flow rates, bypass structures may still be needed. By contrast, many other proprietary systems require complete system upgrades to increase treatment capacity, leading to significantly higher costs.

Ultimately, these differences in performance, cost, and scalability are crucial for long-term satisfaction and budgeting. The best choice depends on the specific needs of the property, including flow rates, site conditions, and maintenance preferences.
